LOCK- SPECIFICATION forming part of Letters Patent No. 313,457, datedMarch 3, 1885.

550 a. whom, it may concern.-

Be it known that I, SAMUEL TUERK, residing at Chicago, in the county ofCook and State of Illinois, and a citizen of the United States, haveinvented a new and useful Improvement in Hinges, of which the followingis a full description, reference being bad to the accompanying drawings,in which- Figure l is an elevation showing my hinge applied to a door.Fig. 2 is a top view of the hinge closed. Fig. 3 is a top view of thehinge open. Fig. at is an elevation of the hinge open, as shown in Fig.3. Fig. 5 is an inside View of the hinge open, as shown in Fig. 3. Fig.5 is a detail; Figs. 6 and 7, modifications of the hinge; Fig. 8, amodification of the spring; Fig. 9, a modification.

The object of my invention is to provide an improved device for holdingdoors, hinged covers, &c., open or partly open in a given position,which I accomplish by providing one leaf of an ordinary butt-hinge witha hinged arm which extends through an opening in the other leaf of thehinge, and is adapted to engage with aspring locatedin a socket, whichmay be either in the door or casing, as illustrated in the drawings.

In the drawings, A represents a piece of door, and B a door-casing.

O D are two leaves of a butt-hinge.

Eis an arm pivoted to the inside of the leaf 0. This arm extends throughan opening, a, through the leaf D. Its outer and free end is providedwith a projection, b, which prevents that end of the arm from passingthrough the opening in D.

0' is a recess in the leaf D, to receive the ears (1 upon the leaf 0, towhich, as shown, one end of the arm E is pivoted.

F is a channel, open upon one side, as shown, which may be cast upon andwith the leaf D. e is a spring secured to the inside of the channel Fand on one side thereof.

One end of the arm E can be passed through the opening a, and thenpivoted to the ears (I.

In use the hinge is to be applied to a door in the usual manner, exceptthat either the casing or the door is to be provided with a socket toreceive the channel F. As shown in Fig. I, this channel is located inthe doorcasing B. WVhen the door is closed, the parts will be in theposition shown in Fig. 2. If the door be opened, so as to stand at rightangles with the casing, the parts will be brought into the positionshown in Fig. 3, the

free end of the arm E passing along over the spring 6 to the free endthereof, and the door. will be held open in that position, requiringconsiderable force to close it. When the door is closed, the free end ofthe arm E will ride over the projecting part of the spring and force itdown. The force which may be required to close the door when it is openwill depend upon the strength of the spring 6.

The form of the spring may be substantially 6 5 as shown in Figs. 2 and3 when it is only desiredto hold the door open at one point. By givingthe spring two bends, as shown in Fig. 8, it will be adapted to hold thedoor either partly open or entirely open. When the door is only partlyopen, the free end of the arm E will be at the point 9, Fig. 8, and thenit will require force either to farther open or to close the door.

By making a slight change my improved In Figs. 6 and 7 I have shown two8 Instead of pivoting one end of the arm E to 8 the opposite leaf, H, ofthe hinge, Iprovide such leaf H with a fixed short pintle, 2 so arrangedthat when the pintle j of the hinge H enters the socket provided for itin the leaf G the pintle i will enter the hole h in the arm 0 E,thusconnecting one end of the arm E with the leaf H.

7c is a recess in the leafH for the end of the arm E. In Figs. 6 and 7the two parts of the hinge are shown bottom side up, in order to 5 keepthe leaf which is provided with the channel F in the same relativeposition as in the other figures. v

I think it advisable to cast the part F with one leaf of the hinge; butthis part might b ICO made separate from the hinge, as shown in spring,6, located either in the door or casing, Fig. 9, and placed either inthe door-easing with which spring the free end of the arm E 10 or thedoor. engages, substantially as and for the purpose What I claim as new,and desire to secure specified. 5 by Letters Patent, is SAMUEL TUERK.
